I think my dad still does.

Uhm, yeah, alas, far too often lists get hit with such requests.
Below I copy boilerplate response (alas, as a listadmin) to seeing far
too many such requests (e.g. emails to listadmins, or posts (or
attempted posts) to lists, much etc.), plus with that, just some
modest changes to make it (more)
eded, and also getting the package state appropriately set to
cleanly installed in the APT database. All seems fine after that.

Relatively quick repair should be feasible.
So ... multi-arch? Is this native amd64 + i386 (I'm
guessing/presuming), or ... is that vice versa?
I'm inclined to similarly break a VM, and then fix it ... shouldn't be too hard.
Anyway, main/primary architecture would be the most critical.

You're configured to follow sid/unstable.
Since things regularly migrate from sid/unstable to testing,
in most regards the installed OS can't tell which you're on, though one
can look at one's APT configuration to see what one is following.
But they may not necessarily be distinguished by what's cu

I think you want delete, rather than erase, so use tput dch1 or tput dch 1.
Erase simply replaces the character(s) with blank(s),

to the left.
E.g.:

With LVM, one can grow LVs, and then filesystems atop that, and
